Purpose: Speech sound disorders (SSDs) can have a negative impact on literacy development, social-emotional well-being, and participation across the life span. Despite this, many public schools do not provide appropriate or timely services to this population of children. In large part, this is a result of variation in how state and local agencies interpret "educational performance" as outlined within the Individuals With Disabilities Education Act. The purpose of this study was to explore which educational performance factors speech-language pathologists (SLPs) consider when determining eligibility for children with SSDs. Method: This study surveyed public school SLPs to investigate how educational performance is interpreted for children with SSDs. Data from 575 SLPs across the United States are included. Results: Results supported variability in interpretation of educational performance within a nationwide sample of SLPs. Specifically, SLPs appear to consider educational performance as multidimensional. We also found within-state and between-states variability, indicating ambiguity in interpreting federal mandates. Finally, caseload size and number of years of experience were significantly related to which educational performance factors SLPs chose. Conclusion: There is significant variability across the United States with respect to factors considered part of educational performance for children with SSD. This variability reflects the general quality and specificity of guidelines and/or special education code published by individual states. Clinical and legislative recommendations are included.
